Toledo Model 8400 Public Health Scale

Due to the lack of a section on Americana I am posting this here. If I am wrong and should post it elsewhere please let me know. I just bought this scale at an auction. It is missing the back door. Does anyone know where I could look to find one? Also, does anyone know a collector in the Florida / Georgia area? I am a dealer so I am looking to sell it. Thank you in advance for any help.
